WRENCH.

To all whom it may concern Be it known that I, WILLIAM J. Mo-

'2 LAUGHLIN, a citizen of the United States,-

residing at Park City, in the county of Summit and State of Utah, haveinvented certain new and useful Improvements in i lrenches, of which the following is a specification. This invention relates to an improved Wrench, and the principal object of the invention is to provide a wrench which is so constructed that it may be used for removing the ends. of broken pipes from sleeves, and which may also be used for in.-

serting and removing nipples.

Another ob3ect of the invention is to so construct the wrench that it may be formed from a single piece of metal having one end portion disposed at an angle to the body portion and provided With longitudinallyextending teeth formed upon opposite sides of the bent end portion so that the bent end portion may be inserted in the broken pipe and then tilted to cause a binding engagement between the wrench and the pipe.

Another object of the invention is to so construct the wrench that it may be used for removing pipes of different sizes. v

This inventionis illustrated in the accompanving drawings wherein Figure 1 is a side elevation of the improved wrench; Fig. 2 is a bottom plan view of the improved wrench; Fig. 3 is a sectional view taken along the line 3-3 of Fig. 1;

and Fig. 4 is a sectional view taken along the line 44 of Fig. 1.

This wrench comprises a body portion 10 which constitutes the handle of the wrench, the body portion being formed from a metallic bar which has its end portions 11 and 12 bent at an angle to the body portion to form arms. These arms 11 and 12 are tapered as shown in Fig. 1, and are provided with enlarged heads 13 which are provided with curved outer faces forming a continuation of the inner faces of the arms 11 and 12. The arm 11 is smaller in diameter than the arm 12, and the head of the arm 11 is smaller than the head of the arm 12 so that the wrench may be readily used for removing pipes of different sizes. The arms are provided upon their inner faces with longitudinally-extending teeth which extend about the heads 13 thusproviding gripping teeth which will cut into the pipe and thus pre vent the wrench from turning in the pipe.

Specification of letters Patent.

Application filed January. 3, 1914. Serial No. 810,234.

It will-thus be seen that when the wrench is lnserted in the pipe and turned, the pipe will be-turned with the wrench and removed from the sleeve.

l/Vhenit isdesired to remove the end of the pipe which has broken close to the end of a sleeve, or whenit is desiredlto insert or remove a nipple, the arm which will fit in the pipe to the best advantage is inserted in the pipe and the handle 10 is then tilted to ring the outer face 15 of the head 13 in engagement with the inner face of the pipe and the inner face ofthe arm in engagement with the outer endof the pipe.

exerting pressure upon the handle, the teeth 1 1 will cut into the pipe, it being, of course,

understood that the wrench is formed of tempered steel, andthe wrench can then be turned in the proper direction to unthread the piece of broken pipe.

. When this wrench is used for inserting" and removing a nipple, the thread of the nipple will not be broken or bent since the wrench engages its inner face and outer end and therefore does not engage the threads formed upon the outer face of the nipple. f

It will thus be seen that the wrench .does

not damage the nipple, and that therefore the board with the board resting upon the face 16 of the head, and then moving the lever downwardly with the curved lower face of the head as a fulcrum. If this does not raise the board a sufiicient distance to release the same, the tool can be turned while still beneath the board to a reverse position so that the curved face 17 will form the fulcrum and the tool can then be pressed downwardly to raise the board a greater extent and entirely loosen the nails which hold the board in place.

What is claimed is:

1. A pipe wrench comprising a body portion, having one end bent to form an arm extending at an angle to said body portion,

said arm being provided at its outer end 1 With an enlarged head provided With a curved end face merging intotheinner face of said arm, the end face of said head and inner face of said arm being provided With its freeend With a head having a curved end face merging into the inner face ofsaid arm, the end face of said head and the inner facevof saidarm being provided with anti-v slipping means. i p

3. Infa pipe Wrench a handle, an arm extending from said handle for insertion into a pipe and providedwith an enlarged head provided With a curved end face merging tinto the inner face Of-Sitld arm, and longlv tudinally-ext'ending grippingribs formed upon the inner face of said arm and extending along the curved face of said head.

In testimony whereof I affix my signature J in presence of two Witnesses.
